Abstract

Life in the oceans is strongly connected to our climate. In this workshop, you will learn to use packages from the JuliaOcean and JuliaClimate organizations that provide a foundation for studying marine ecosystems across a wide range of scales. We will run agent-based models to explore individual microbes and processes that drive species interactions. On the other end of the model hierarchy, we will simulate planetary-scale transports that control ocean biogeography and climate change.

Notebooks

Any example found in the online documentation is most easily run using Pluto.jl .

Just copy the corresponding notebook url link below and paste into the Pluto.jl interface (v0.15 or later).

Description

Packages covered in this workshop include:

AIBECS.jl: global steady-state biogeochemistry and gridded transport models that run fast for long time scales (centuries or even millennia).
PlanktonIndividuals.jl: local to global agent-based model, particularly suited to study microbial communities, plankton physiology, and nutrient cycles.
MITgcmTools.jl: interface to full-featured, Fortran-based, general circulation model and its output (transports, chemistry, ecology, ocean, sea-ice, atmosphere, and more).
IndividualDisplacements.jl: local to global particle tracking, for simulating dispersion, connectivity, transports in the ocean or atmosphere, etc.

The workshop was organized around tutorials and self-contained Pluto notebooks for the different packages.

Setup instructions

To run the notebooks of this workshop on your machine, you need to:

Install Julia from https://julialang.org/ (latest version is v1.6.2)
Start Julia
Add Pluto.jl (v0.15.0 or later)**

This is simply done by typing, in the julia REPL,
```
import Pkg
Pkg.add("Pluto")
```
Note: Please make sure you get version 0.15.0 or later. If you get an older version then you can add Pluto in a clean, temporary, environment as follows:
```
import Pkg
Pkg.activate(mktempdir())
Pkg.add("Pluto")
```

Use Pluto to run the notebooks. This is as simple as copy-pasting one of the following lines, depending on which notebook you want to run:

using Pluto
Pluto.run(notebook="https://raw.githubusercontent.com/JuliaOcean/MarineEcosystemsJuliaCon2021.jl/main/src/AIBECSExample.jl")

Alternatively, instead of your own computer, you can just launch a Pluto instance in the cloud using JuliaHub.com, paste a notebook URL in the Pluto start page, and click open.
